There are three types of messages between w1 core and userspace: 1. Events. They are generated each time new master or slave device found either due to automatic or requested search. 2. Userspace commands. Includes read/write and search/alarm search comamnds. 3. Replies to userspace commands.

Special file in each w1 slave device's directory called "rw" is created each time new slave and no appropriate w1 family is registered. "rw" file supports read and write operations, which allows to perform almost any kind of operations. Each logical operation is a transaction in nature, which can contain several (two or one) low-level operations. Let's see how one can read EEPROM context: 1. one must write control buffer, i.e. buffer containing command byte and two byte address. At this step bus is reset and appropriate device is selected using either W1_SKIP_ROM or W1_MATCH_ROM command. Then provided control buffer is being written to the wire. 2. reading. This will issue reading eeprom response. It is possible that between 1. and 2. w1 master thread will reset bus for searching and slave device will be even removed, but in this case 0xff will be read, since no device was selected.

Now /sys/class/usb is dynamically created when we have something to put in it, and removed when all devices go away. Just trying to cut down on the clutter in sysfs... Signed-off-by: -

This moves the usb class devices that control the usbfs nodes to show up in the proper place in the larger device tree. No userspace changes is needed, this is compatible due to the symlinks generated by the driver core. Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: -

This patch adds IXP465 into the list of known devices and adds IXP425 and IXP465 to the list of devices that have cfr. This is not described in the hardware documentation, but without it driver won't work. Workaround (#if 1) that seemed to get rid of lost status irqs is disabled for IXP4XX as it caused freezes during testing of control messages. No lost irqs are visible on IXP4XX. Driver survived tests running over night without any visible problems. Signed-off-by:

When closing the device, the driver acquires/release twice the port lock before/after waiting for the data to be completely sent. Therefore it will dead lock. This patch fixes it and also uses the generic scheduler services for waiting for an event. Signed-off-by:

If either the driver's open() method or try_module_get() fails, we need to set 'tty->driver_data' and 'port->tty' to NULL in serial_open(), otherwise we'll get an OOPS in usb_device_disconnect() when the device is disconnected. Signed-off-by:

This is a new driver for the Cypress CY7C63xxx mirco controller series. It currently supports the pre-programmed CYC63001A-PC by AK Modul-Bus GmbH. It's based on a kernel 2.4 driver (cyport) by Marcus Maul which I ported to kernel 2.6 using sysfs. I intend to support more controllers of this family (and more features) as soon as I get hold of the required IDs etc. Please see the source code's header for more information. Signed-off-by:

This update contains one bug fix: some lines can come out truncated, because of the safety cutoff. This happened because I forgot to update the size when status packets began to be printed. The rest is: - Comments updates - Allow snooping with pkmap on x86_64, which is cache-coherent - Enlarge event buffers (certainly we can have a couple of pages) - Add event counter First touch upon usbmon for 2.6.18.

This patch (as707) improves the FSBR operation in uhci-hcd by turning it off more quickly when it isn't needed. FSBR puts a noticeable load on a computer's PCI bus, so it should be disabled as soon as possible when it isn't in use. The patch leaves it running for only 10 ms after the last URB stops using it, on the theory that this should be long enough for a driver to submit another URB if it wants keep FSBR going.

This patch (as706) removes the private hc_inaccessible flag from uhci-hcd. It's not needed because it conveys exactly the same information as the generic HCD_FLAG_HW_ACCESSIBLE bit. In its place goes a new flag recording whether the controller is dead. The new code allows a complete device reset to resurrect a dead controller (although usbcore doesn't yet implement such a facility). Signed-off-by:

This patch (as705) contains a small set of updates for uhci-hcd written mostly by Dave Brownell: * Root hub suspend messages come out labeled as root hub messages; PCI messages should only come out when the pci device suspends. * Rename the reset() method to better match its init() role * Behave more like the other HCDs by returning -ESHUTDOWN for root-hub suspend/resume errors. * When an URB fails, associate the message with the usb device not the host controller (it still hides endpoint and direction) From: David Brownell <david-b@pacbell.net> Signed-off-by: -

This patch (as703) improves the error handling when a Set-Configuration request fails. The old interfaces are all unregistered before the request is sent, and if the request fails then we don't know what config the device is using. So it makes no sense to leave actconfig pointing to the old configuration with its invalid interfaces. Signed-off-by:
